# How to subdivide many complex meshes?

I created a globe. Each country has its own mesh, because I need it like this for an app development.

Currently, all meshes are big n-gones, which is not great for the deformation. Now, I am searching for a way to subdivide the meshes. I was already successful using the knife tool. But in this case, I need to create a plane, go in the edit mode... And I need to do it for over 200 meshes.

Maybe, somebody has some experience and knows how to do it in a faster way.

If I triangulate the faces and use the subdivision modifier, I does not look great, because of the edges.

One idea is to create a flat subdivided cube in the geometry nodes I am using. And afterwards lay it on country mesh and use the boolean node to receive a copy, which is subdivided and has the same transformation. But I do not know how to do it.

• Unfortunately that will not be an easy task. Mostly manual work. Or you could try remeshers like Quad Remesher (really good but paid addon) or the free built-in Quadriflow Remesher but is not so good. Commented May 7 at 5:04
• There's also the software called Instant Meshes but maybe share your file so that we can give a try (share only a part of it)? Commented May 7 at 6:48
• @moonboots You can get the meshes from the file in his last question. Commented May 7 at 6:49
• @Gordon Brinkmann Oh ok thanks ;) Commented May 7 at 7:56
• @HarryMcKenzie I tried Quad Remesher. It is good, but not perfect enough. I have gaps at the borders. Unfortunately, the knife tool was still the best. Commented May 7 at 11:55

• @PascalMeger If these are still the same meshes from your last question, triangulating will help absolutely nothing here - because they are already triangulated, just in very large and useless triangles. Together they have 90,537 faces and 90,537 triangles, so there are no quads or n-gons, all tris. And after triangulating with Ctrl+T the number of tris is still 90,537. Commented May 7 at 6:08
